Injjthe drawing forming a part of this specication and wherein lke'nurnerals are employed tolde's'gnate like partsthroughout the same z'v Fig. 1 is a side elevational view of a nozzle embodying the invention andshowing the same' attached toa fragmentary hose portion;

Fig`2l is an enlarged, transverse sectional view comprises an "elongatedv body IG which conveniently can be made of plastic or the like. .The body l0 is slightlygcurvedasat I2 and the inner end-|4thereof isl's'liglfrtlyenlarged to define a radial shoulder I6. Projecting from the shoulder I6 is a shank I8 of materially reduced diameter and the shank is formed with a plurality of' longitudinally spaced externalgrooves'il. As clearly shown in the drawingZ the shank i8 is adapted for insertion" into a rubber tubing 22 or the like The tubing 22 preferably is pushedonto`V the shank I8 luntil it abuts against shoulder'l. )Infl the form 'of' the invention shown, the shank 1' |81 is slightly larger than d 4thejjinternal passage rj of. the tubing so that the latter is stretchedA slightly by insertion ofthe 'shankiAs a result,.; the rubber material of tubing 22 tends to now into grooves 20 and thus assists in holding the tubing von the shank.

The distal terminal portion of the shank I0 is radially enlarged and is formed with a plurality of longitudinally spaced, annular, external grooves 24 each of which extends entirely around the shank. As clearly shown inthe drawing, the grooves 24 define a plurality of intermediate wartend Harold t'. remweg, Detroit, Mich.

Vlongltudinzril passage 28 extends ventirely;A through`v the body Illgand the portion vof thepassage extendingI Athrough the enlarged terminal` portion 'ofthe-'body is radially enlarged'tofdeV-m ne man" annular radial shoulder; 3B vat theinnerl or proximal .end 1of Athe; enlarged 'portiong j The enlargedportion'of the passagadefines a chamber 32 'whichis adapted toY receive a douche powr' der, pill, or other medicament in use. pj

Closing into the open distal Aend of the ber 32.is"a.cap v34; .As perhaps bestshownjnjf Fig. 3 thecap' 34 has an Aexternally screw-threads ed shank portion 36 which extends into the cham.-

ber"32 and a' radial shoulder`138 which abuts the end of the bodyll).A TheV shoulder 38 extends. outwardly radiallyV beyond the adjacent confront. ing end of the body l0 and is rounded, asat 4, to define a terminal annular ridge dil. Also, the cap :i4-preferably is peripherally concaved, as at 42, immediately in front of the annular ridge :40. The cap 34-is formed with a hollow interior 44, arid a.generally"cup#shaped screen 45 is press tted into thecap. In this Vconnection it will be observed v'that the'screen 4B-has aclosedendllt within the cap and that the screen extends from` the cap to-seat against the annular shoulderx The seated distalfend of thescreen preferably is strengthened orv reinforced by a surrounding metal ferrule 5V2. --Radial apertures fconnectthe chamber 32 with each of -the grooves 24 and the Yinterior ofv cap 34with the concaved surface- 42 and with'the end surfaceofV the cap.

- From the foregoing it will bel readily apparent; that the cap 34 is readily removable from thebodyIllV andthatrthe screen 46 is removable withqthe cap.-;A Sincethechamber 32iszadapted toi-,receive anmedicament it is desirable to remove 1 theicap 34 periodical,ly-j so that the wall of the chamber .can befcleaned. Also, the cap and screen assembly prcvidesa convenient means of inserting:Inedicamentjnto the chamber. Whenthe cap 345i's :removed-,fthe -screen 46 is' readily accessible andi:themedicamentK canbe readily introduced intoxthe'open distal end thereof.v After the medicy n ament has been inserted into the screen, the latter is inserted into the chamber 32 and the cap 34 is screwed tightly in place. Manifestly the medicament is introduced into the chamber 32 with the screen. A nontoxic screen which is inert to water and the medicament used in the device preferably should be used, and anysuitable size mesh can be employed. The primary purpose of the screen is to confine the medicament and to through the hose and; into the nozzle El Where, i

it is discharged through-the radial apertures 50. Since the water must flow through the screen 4S before entering apertures 59 and since they;

medicament is confined Within the screen, it

continuously dissolved in the Water as it iio'vvs through the nozzle. cated solution is discharged from the nozzle.

In addition to the above, the provision of external annular grooves 24 makes the'nozzle supe= Thus, a continuous. medirior to conventional devices of this type which1'L conventionally are provided with circumferentially. spaced. longitudinaLeXternal grooves; The- A latter construction .brings the v .Waterin -Qontact whereas/ the instant device-.will erect a complete contact-Etherewithfand, assure .a more thorough., cleansing action.. in this connection ,it will, be,
